1 Claim. (Cl. `1mm-2149.4)

This invention relates `generally to hectographic addressing, and more particularly -is concerned with a carrier for use with high `speed addressing equipment which has `a novel `address field or Ipanel.

Carriers for use with this type of apparatus have been constructedin the form of a frame lhaving the-address field or panel secured to one side byrneans of pressuresensitive adhesive, such panels being typewritten on conventional flexible members in the usual manner. `The eitective exposed `faces of such panels is of course reversed, and the crispness of reproduction depends upon the sharpnessof exposedlettering. A difficulty with such conventional carriers has been `that in using the carriers in themachine, the lettering becomes worn and blurred because the carriers must-be placed on top of one another in the machine. An additional difiiculty with prior carriers has-been the need `for a separate tile of addresses for the carriers, therevbeingno space provided for identitying entries.

Other carriers have been used in high speed addressing which are in the form of index cards provided with windows in which the address panel orslip is glued. Such carriers are oftenassociated with account forms and the like, but require that the entire card be passed through a typewriter, whichrhas an adverse eEect upon the atness of the carrier. In addition to the field being unprotected from wear, `in this case, transportation of the carriers through the machine is inefficient because .of bends, buckling and the like caused by running the cards between typewriter rollers. Some of the prior carriers which are in the form `ofdndex cards glue an address blank between front'and rear parts of the carrier, but since the carrier mustnalso be passed through a typewriter in order to apply the address or other intelligence, these carriersrareasubject to the same disadvantages as the others mentioned above.

An important object ofl the invention` is the provision of a hectographic carrier for use is high speed addressing machines which will alleviate and eliminate the disadvantages of prior carriers.

Still a further `object ofthe invention is to provide a carrier in which there is `an address eld or panel which is secured to the carrier in a simple and effective manner to protect thelettering of the address and to preserve the planar ilatness of ythecarrier so that the same can be passed through the` addressing machine efficiently.

Still a further object of the invention is to provide a carrier in which the'field or panel is of a form which is easily typewritten prior to assembly to the carrier,.and after such preparation'is applied to the` carrier by` means of pressure-sensitive adhesive in a novel recess provided therefor in the carrier.

An additional important object of the invention lies in the provision of a carrier for use in high speed hectographic addressing in which the address field or panel is spaced from the surface of the carrier and thereby protected in handling of the carrier, and further, in which the carrier is perfectly at and devoid of bulges enabling compact and even stacking.

ICC

Of considerable importance is another object of the invention, and that is the provision of a carrier in which although the field or panel is glued thereto vby some suitable adhesive, nevertheless the stacking of a considerable quantity will not result in bulges formedin said stack.

Many additional objects and advantages of Athe invention will occur to'those skilled in theart to which this invention appertains,`and these will becomeapparent as the description thereof proceeds. 'In connection with such description there has -been illustrated and set forth in con siderable detail a preferred embodiment lofthe invention, from an inspection of which the invention-will'be fully understood and appreciated, and the` advance-in 4the Varts and sciences which is represented by theinvention'will be demonstrated.

In the accompanying drawing:

Fig. l is a top plan view of a carrier'constructed in accordance with the invention hereof;

Fig. 2 is a bottom plan view of the same;

Fig. 3 is a view similar to that of Fig. l but showing the manner in which the address field or` panel is appliedto the carrier;

Fig. 4 is a sectional View along theI line IVIV of Fig. 3 and in the direction indicated;

"Fig.5 is a top plan View of a perforated `strip of' address fields or panels which are associated with the carriers of the invention.

Generally the invention comprises a carrier which is `formed of a pair of laminated members each provided `rabbet or` ledge and adhered in place. The combining of the two` parts of the carrier may advantageouslyinvolve the use of `a pressure-sensitive adhesive compatible ,with the adhesive applied around the edges` of the address slip. Thus, when `associated together, the ledge and` edgesof the slip will adhere in tight engagement. The typewritten address slip will usually be of a flexible materialtransparent in nature, or at least of a composition which ,will expose upon its rear face the mirror image of the type- `written intelligence so that the treated surface to which the same is applied will receive the proper and exact reproduction of the typewritten matter. Such flexible material is preferably substantially thinner than thematerial of either part of the carrier so that the address slip is recessed both front and back and hence fully protected during handling and use. The thickness of the panelvcould be as much as the depth of the rabbet without adversely affecting the handling and stacking qualities of the carrier.

Referring now to 'the illustrations, the referencecharacter 1 is used generally to designate the carrier ofthe invention, and 2 designates the address field or panel adapted to be applied to the carrier. The surface fof the carrier may be in the form of an index card,` account form or the like, with spaces Vfor suitable entries. The carrier 1 is formed of two parts laminated together by any suitable adhesive or adhering agent 1', there being a front part 3 and ya rear part 4, both having their peripheral dimensions and contours identical to form a unitary assembly. The material from which the front and rear parts are formed may be cardboard or the like, although other materials such as thermoplastic resins and combinations thereof with paper or cardboard may also be used. Conveniently, the parts are adhered by glue or paste of the conventional varieties, or by means of a pressure-sensitive adhesive of some kind. In the case of plastic or part plastic sheeting, the adherence may be achieved by heat, by electronic welding or the like. Likewise adhesives sensitive to heat may be used.

The carrier 1 is shown as having rectangular form with rounded corners, although it should be appreciated that this is only by way of illustration 'and not to be considered limiting. Likewise, the rectangular window 5 formedhin the upper portion of the carrier is only an example of the kind of window which can be used. The window 5 is formed by reason of the rectangular opening or cut-outs 6 and 7 die-cut or otherwise formed in the respective parts 3 and 4. The opening 6 is smaller than f the opening 7 so that with the openings aligned, that is, -having substantially equal peripheral spacing one relative the other, there will be formed a ledge or rabbet 8 immediately adjacent and around the opening 7. Access to the rabbet 8 is had from the front face of the carrier 6, and as indicated by the shading, this rabbet has an adhesive thereon, applied either in the process of manufacturing the` carrier 1, or thereafter'.

Theaddress fields or panels 2 `are formed with contours and dimensions such as to correspond Asubstantially yto the opening 6, so that a panel 2 may be laid upon the rabbet 8 and retained upon the carrier. Preferably, the address fields or panels 2 are formed in strips such as illustrated in Fig. 5, separated by perforations 9 -and pre-gummed about their edges as indicated by the lrolls and readily and quickly run through a typewriter prior to being applied to the carriers.

'Ille adhesive 9 of the address fields or panels is preferably of the pressure-sensitive type, compatible with that applied to the rabbet 8 in order to secure a good bond.

In using the invention, if it is desired to apply an -address slip or panel 2 to a carrier, the strip of fields is threaded through a typewriter and the necessary information typewritten upon the face of the panel 2 in the area 10. The adhesive 9 is on the rear of the panel 2. -The panel is separated from its adjacent counterparts at a row of perforations 9, and the eld is then applied to l the carrier by laying the same into the front of the window 5 with the mirrored printed matter exposed from the rear through the opening 7. Thereafter the adhesive is caused to adhere by pressure or any other method required for the particular adhesive used,

It is preferred to use pressure-sensitive adhesive for the advantage that when desired, the address slip or field 2 can be removed from the rabbet 8 without in any way damaging or `disturbing the carrier 1, and replaced by a new iield. This gives rise to considerable economy which can be practiced with the invention. In connection with the removability of the address lield or panel 2, the opening 6 is not perfectly rectangular but instead is provided with a slightly outwardly extending enlarged portion, shown at the bottom of the opening 6. Thus, thisy bottom edge departs from parallelism with the top edge of the opening 6, and since the slip or panel 2 is 4 rectangular, when assembled together there will be a groove or recess 6 formed between the edge of the slip or panel 2 and the opening 6.

If it is desired to remove the slip or panel 2 for replacement, a sharp instrument may be inserted into the recess 6' to initially strip the panel 2 from its seated position. This can easily ybe done manually, with ones linger nail, if desired. Obviously the recess 6 may be in the form of any conliguration to assist in obtaining purchase of the panel 2 for its removal.

It should be appreciated that the carrier 1 may be formed of an integral member of cardboard, plastic or other relatively rigid sheeting, having the window 5 cut therein, with the rabbet or ledge 8 formed by molding, embossing, or other known process. In any event, the faces of the address field or panel 2 are preferably spaced below the surfaces of the carrier, and hence protected in the manner previously explained.

Considerable variation in the minor details, proportions, and size and shape of the elements of the invention are capable of being made without in any way departing from the spirit or scope of the invention as dened in the Iappended claim.

What it is desired to secure by Letters Patent of the United States is:

A carrier for hectographic reproduction comprising, a relatively thin iiexible sheet member having a window extending therethrough, a recessed ledge surrounding the window in the front face of the carrier, an extremely thin, exible address panel having an area of pressuresensitive adhesive on its effective face adjacent edges thereof, said panel being adhesively secured upon said ledge with its effective face exposed through the window from below the rear face of the carrier, said panel and ledge being substantially congruent but with the panel slightly smaller to t within the recessed area of the front face defined by the ledge, said sheet member being formed of two laminations adhered together, each lamination having a cut-out therein respectively aligned one relative the other to form said window, one of the cutouts being slightly larger in dimension than the other whereby to overlap one the other to form said ledge, the depth of the ledge and the thickness of the panel being selected so that the surface of the panel opposite the surface thereof exposed through said window is substantially Hush with said front face of the carrier, the larger cut-out having an outwardly oiset portion along one edge thereof to expose the ledge upon which the panel is secured whereby to permit insertion of means between the panel and ledge at the location of said offset portion to remove said panel without damage to the carrier.
